A mimic diagram is provided on the control panel. The main components of the electrical apparatus can ensure the safety of the controlling system. The interlocked protective system and pressure protective device which will avoid overload, over voltage, pumping without oil, heating without oil, oil leak, electricity leak and prevent any damages to equipment due to operating error or power failure. Heater The unit equips a digital temperature controller as a safety thermostat, which has a reliable thermocouple mounted in a pocket inside the vessel. The temperature can be set by manually and with capable of heating oil from 20 C to 80 C. The designed temperature range can protect the safety both device and worker. The deterioration of the oil caused by overheating is avoided. Heating elements is made in refractory formers and don t directly contact with oil so that localized overheating, hot spot and breaking of oil is avoided. The heating components can warm up temperature around and heat radiation, container can uniformly warm up the oil, adopting low load of heated surface, less than 1.5W/cm2. The heater has safety protection device with, which can avoid heating without oil. It is secure and reliable. Construction of the heat exchanger shall be such that the replacement of heaters is easy and shall not require any special tools. A drain for the heater tank is provided.
Inlet & Outlet Pump (Inlet pump are optional) Inlet pump(optional): Positive displacement gear type driven by electric ; flow control & pressure safety against over-pressure is provided. Interlocking arrangement is provided between the inlet pump and the heater I, so that the heater cannot be energized unless inlet pump is ON. Interlocking arrangement between the inlet pump and high level switch avoid excessive rise of oil in the vacuum chambers. Discharge Pump: suitable for sucking oil from the vacuum chambers held under vacuum. This is fully tested for pressure and vacuum leak rate. The pump is of robust construction and capable of developing pressures of up to 200 PSI. Interlocking arrangement is provided between low level switch and discharge pump to prevent dry running of discharge pump. Vacuum Pump A rotary vane vacuum pump is a sort of vacuum production equipment, it is suitable for pumping air and make the oil purifier working under high vacuum status.

It is possible to clean the strainer without dismantling the filter. Oil Coalescer(optional): This coalescer oil water separating filter elements are made of specialized glass fiber, which can remove free and emulsified water from oil. When free water is more than 1000ppm, we suggest to choose the coalescer. Fine filter: This filter element allows to accept a standard filter separating particles as small as 1 micron. Pressure and pressure protector is provided on the filter vessel in order to ascertain condition of cartridge elements and avoid the overpressure. Liquid-level Controller The automatic electric float ball switch is provided in the vacuum chambers to protect the vacuum chamber from overfilling and too low oil. It connects with inlet/outlet pump, electromagnetic to control balance of inlet and
